To configure the backlighting, `#define` these in your `config.h`:
-| Define | Default | Description |
-|------------------------|---------------|-------------------------------------------------------------------------------------------------------------------|
-| `BACKLIGHT_PIN` | *Not defined* | The pin that controls the LED(s) |
-| `BACKLIGHT_LEVELS` | `3` | The number of brightness levels (maximum 31 excluding off) |
-| `BACKLIGHT_CAPS_LOCK` | *Not defined* | Enable Caps Lock indicator using backlight (for keyboards without dedicated LED) |
-| `BACKLIGHT_BREATHING` | *Not defined* | Enable backlight breathing, if supported |
-| `BREATHING_PERIOD` | `6` | The length of one backlight "breath" in seconds |
-| `BACKLIGHT_ON_STATE` | `1` | The state of the backlight pin when the backlight is "on" - `1` for high, `0` for low |
-| `BACKLIGHT_LIMIT_VAL ` | `255` | The maximum duty cycle of the backlight -- `255` allows for full brightness, any lower will decrease the maximum. |

Unless you are designing your own keyboard, you generally should not need to change the `BACKLIGHT_PIN` or `BACKLIGHT_ON_STATE`.
